Quantification of siderophore and hemolysin from Stachybotrys chartarum strains, including a strain isolated from the lung of a child with pulmonary hemorrhage and hemosiderosis

A strain of Stachybotrys chartarum was recently isolated from the lung of a pulmonary hemorrhage and hemosiderosis (PH) patient in Texas (designated t he Houston strain). This is the first time that S. chartarum has been isola ted from the lung of a PH patient. In this study, the Houston strain and 10 strains of S. chartarum isolated from case (n = 5) or control (n = 5) home s in Cleveland were analyzed for hemolytic activity, siderophore production , and relatedness as measured by random amplified polymorphic DNA analysis.
